Greensmith Energy, a leader in advanced energy storage software and services, E.ON Climate and Renewables, and Tucson Electric Power (TEP) will host a ribbon-cutting ceremony on June 1 to inaugurate the Iron Horse Battery Energy Storage Project.

The 10 megawatt (MW) / 2.5 MWh energy storage system at the University of Arizona Science and Technology Park will provide frequency response and voltage control. The project illustrates the growing trend of programmable battery storage replacing fossil generation as the least-cost solution for grid reliability services. The system also provides integration for a new 2 MW solar array.

Greensmith provided design, integration and commissioning of the turn-key energy storage system that leveraged LTO (lithium titanate oxide) batteries suitable for high frequency, high power applications. The company's industry-leading GEMS software control platform will deliver real-time monitoring, integrated control and system optimization and safety throughout life.

"Fast-responding energy storage software will be critical for maintaining grid stability as the Tucson area prepares to add hundreds of megawatts of new renewable energy capacity in the years ahead," said Greensmith CEO John Jung. "We are proud to partner with E.ON to help make Tucson Electric Power's clean energy vision a reality."

Greensmith announced its participation in the Iron Horse project last summer, following project approval from the Arizona Corporation Commission for a ten-year agreement to use the project for ancillary services. Greensmith, E.ON, and TEP broke ground late last year.

On May 15, Greensmith announced that Wärtsilä (Nasdaq OMX Helsinki: WRT1V), a global leader in advanced technologies and complete lifecycle solutions for the marine and energy markets, has signed an agreement to acquire the company. The transaction, subject to US regulatory approval, is expected to close by July 2017.
